ValidationSummary inside RadNotification

Rama

I have my validationsummary control in the ContentTemplate of RadNotification and it used to work perfectly fine until I have upgraded the Telerik to the latest version. It is now not displaying the validation summary but pops up a blank notification. It actually displays anything that I add in the contenttemplate but not the validationsummary.
Do you think there is anything that has knocked out in the latest version?

Thanks for your response.
I just figured the problem is with the web config file where it says <httpRuntime targetFramework="4.5" />.
The ValidationSummary is displaying when I remove that line and vice versa.
Apologies for the panic, although I am little bit hazy why it doesn't work with the targetFramework tag on.
